AUTO HOOD LOCK.

Applicationeled January 18, 1923.

To all #jj/wm t may concern.'

Re it known that l, CHARLES Bonn, a citi.- Zen of Poland, residing vatNew Britain, in the county ot' Hartford and State of Connecticut, haveinvented certain new and usevlul lmprovements in Auto Hood Locks, otwhich the following is a specification.

My invention relates to improvements in auto-hood locks having referencetoV the clamp ystructures that are used on automobiles for clamping thehood in the closed position over the engine structure and adjacent partsand the object of my improvement is to incorporate in the structure of ahood-clamp a key controlled lock so as to prevent unauthorized openingof the hood and tampering with the engine or other parts such as areusually enclosed within the hood, involving the use ot one or `moreclamps in accordance with my improvement on each side of the hood andreplacing a corresponding number of the clamps of ordinary form. i

In the accompanyingdrawing Figure 1 is a side elevation of part of thestructureof an automobile showing the hood and the adjacent part of thechassis and with a hood clamp made in accordance with my invention,provided with a key-controlled lock, the key also being shown in place.

Figure 2 is a similar view on an enlarged scale of the hood-clamp shownin Fig. 1 and adjacent parts.

Figure 3 is a plan view of the same.

Figure 4 is a similar View with the top cap turned to the closed orcovering position.

Figure 5 is a front View of the same.

Figure 6 is a sectional view on the line 6-*6 of Fig. 3.

Figure 7 is a similar view with the parts in the unlocked position andthe hook free to be turned on its axis.

My improved auto-hood lock involves the use of a structure thatcomprises essentially the combination of an auto-hood clamp structure 10and a key-controlled lock structure 11 and which structures areintimately associated, as will be described.

The clamp structure or clamp proper 10 is pivotally connected by itslower end 12 with the chassis 13 and has at its upper end a laterallypositioned and downwardly directed hook 14 that in the locked positionis engaged with an opening 15 in an eye piece Serial No. 613,319.

or lug 16 that is supported from the side wall of the hood 17.

,Said hook 14 comprises the laterally directed connecting portion 18that extends outwardly from the adjacent side wall 19 and the tree arm20 that `extends downwardly from the outer end of said connectingportion 18, said free arm being the part that is actually engaged withthe opening 15. Between the free arm 20 and the adjacent side wall 19 isan open space 21 in which is housed the end wall or enclosing wall 22 ofthe eye structure or eye lug 16, and which space 21 is substantiallylled by said lug 16.

As will be described, the lug 16 serves as the keeper for the lockstructure 11 and to this end it is provided in the end face that isopposed to the side wall 19 with an opening 23 that is adapted tocooperate with the engagingfree end of the locking bolt 24.

Like the hoodclamps in vlcommon use the hood clamp structure 10 iscomposed of two main parts'that haveoverlapping and loosely telescopingportions and that are held operatively positioned one relatively to theother by means of a coil spring 25.

Said parts comprise the vupper part 26 that carries the hook 14 and thevlower part 27 that has the pivotally connected lowerend 12.

The lower part 27 above the hinge connection or pivotal connection isgenerally in the forni of a rod that terminates at the upper end intheform of a head 28 that cooperates with the opposed upper end of thespring 25.

The upper part 26 comprises a body portion 29 of appreciable length andof generally cylindrical form oi larger diameter than the rod structureof the lower part 27, has the hook 14 adjacent the upper end, supportedby the connecting portion 18, and has just below said connecting portion18 a transversely directed chamber 30 for the bolt 211 and for a backingspring 31 for said bolt.

The lower end portion of the body portion 29 overlaps the lower part 27and has an internal chamber 32that is closed at the bottom by means of ahead 33 and in which chamber 32-is housed the spring 25 and the-cooperating portion of the lower part 27.

As described and as is common, the upper part 26 and the lower part 27are connected by means that permit of lifting the hook 14 so astodgisehgage` f1-rom: t'lifev'feye structure provided.v bythe lugl andthe/n"v turning the hook to one side, the lifting being inoppovsit-iorrt-o`the'springZi which tends to draw the parts together;`.Y

At the eXtreme upper end ot the body porftion 29 is a `laterallyvdirected hook-like as aclosliir'e orccover for the extreme endfacelotthebody portion 29,'bing provided with a pivotal .connection 36that is posiy tioned adjacent the handle`34. Said )ivotal connection` 36comprises a spring 31 that servesl to provide a`y1eldmg connection for.the parts;

The lock structure corresponds' generally Y to thet-ormknown asacylinder or pin lock.

lent.

As shown7 .saidY lock structure has a key 38 .eigene-rally flat'tormwith thensual undulating operating edge for operating a set 39 ofspring-'pin tumblers. The` key 38 serves release the cylinder or barrel40 so that thefsameeanbe rotated. Adjacent thelower .eV-ndlof'th'ejbarrel Onis a slot 4l in theY periphery Vthatcooperates' with apositioning pin 4:2that servesto positionv and also to limit the"roftative movement of the barrel' 40.

. VThe extreme lower end portion L3 of the barrel 40 is operativelyconnected with the bolt 24r in any proper Vmanner as by` means ofcooperating earn portions or the equiva- The parts are constructed andarranged so that whentheiclamp'structiue is brought to'the properclamping position for holding the hood in place and released the boltwill engage with the keeper provided by the lug- 16 and in order to'release the clamp it will be necessary to use the key for operating thelook.

I claim as my invention 1. In combination in an anto-hood lockstructure, a chassis of an automobile and a hood supported thereby, saidhood having a laterally directed lug that has an eye opening, ahood-clamp structure of generally vertically elongated form that ispivotally connected b v its lower end to said chassis and is provided atits upper end with a hook for being engaged with said eye` opening, saidhood-clamp structure comprising two main parts that are connected forrelative movement, said parts comprising an upper part that supportssaid hook and a lower part that has the above mentioned pivotallyconnected lower end, said lug and upper part having in the engagedposition opposed and adjacent wall portions, a lock supported by saidupper portion, and said lock having a bolt for locking together saidopposed and adjacent wall portions'.

2. In an auto-hood lock structure as described in claim 1, said upperpart having a laterally directed handle lug at the upper end and havinga key-hole opening in the Yupper face, and a key-hole cover pivotallysupported by said handle lug and adapted to be swung over and cover saidkey-hole opening;
